MPRQVEMENT IN -MORTISINGCHISEL l *w* I The Schedule referred to in these Letters Patent and making parl: of the lime.

To all whom it may concern Be it known that I, MICHAEL FEIGEL, of New Utrecht, Kings county, and State of New York, have invented 'a new and usehl Improvement in Mortising- Ghisels and do hereby declare that the following 1s p ageneral description thereof, referenee being had to the 'accompanying drawihgsfmaking part of this spegenerally. used for cutting moxtises in wood, for reception of tenons, eonsistsin constructing a chisel with a cutting-blade at its back, so 'that at each cut of the chisel the bres of the wood in rear of the chisel will" be cut to the depth to.whi,ch the,chisel descends, and

on the return of the his'el from the wood, will draw up the chips with it, leavingraclear space in rear of the chisel after each stroke, andl making roomfway for "the next stroke of the chisel, by means of Ywhich a greater amount of work can be performed in the same time, and a consequent saving of labor aud expense obtained; besides, the fibres of the wood being cut and drawn out of the mortise by`my chisel, makes better l work than where the fibres arethrced or torn from the mortise, as is the casein operating with the ordinary My improved mortisin g-chisel is particularly intended to be operated by machinery, but it can in like manner be used by hand.

In the accompanying drawings- A indicates the chisel;

C, the front;

D, the rear;

d, the cutting-end; and

E, the cutting-blade, attached to the rear, D, of said chisel.

This cutting-blade E is forged in one piece with the chisel, and is located near the centre of the back of the chisel. It is slightly curving, andleans to one side, for the purpose of embracing the chips and drawing them out with the chisel. It also has a cuttingedge, a, as shown in thedrawings.

I am aware thatchisels having cutting-wings at right angles to the4 cutting-face of the chisel, so as to form three sides of a square,v have been used, to which p I lay no claim.

I am also aware that curved blades, for forming tenons projecting from the 'edges of the chisel, have been used, and I do not claim such; but

What I claim as my invention, and desire .to secure by Letters Patent, is

The 1nortising-chisel A, provided with the cuttingblade E, projecting obliquely from near the middle of the back thereof, and operating as and for the purpose herein specified.

'In testimony whereof, I have hereunto set my signature, this 27th day of November, A. D. 1868.

MICHAEL FEIGEL. Witnesses:
